SIGN WRITING PEN Samuel Halpern, Philadelphia, Pa.

Application February 23, 1933, Serial No. 658,029

2 Claims.

This invention relates to improvements in the type of pens commonlystyled fountain pens and the primary object of my invention is toprovide a pen having relatively wide nibs that can be efiioiently usedfor writing or printing signs and for heavy lettering.

An object of this invention is to provide a fountain pen having areservoir for ink or other writing fluid stored within a tubular handleand having an elastic air-bulb at the end opposite the nibs for raisingthe writing fluid into the tubular handle.

Another object of this invention is to curve the nib-end of the pen soas to form an arcuate outward portion or elbow in obtuse angularrelation with the upper face of the tubular body and having flattenedside walls terminating in a ribbun-like orifice.

Another object of this invention is to bevel the nib portion outwardlyat an oblique angle from the near side to the far side and to provide aplurality of serrations or slots in the nib portion so as to insure aneven discharge of the writing fluid.

Another object of this invention is to round the bevelled outer edges ofthe nib portion so as to permit variation of the writing angle withoutdamaging the paper or surface written upon.

Another object of this invention is to make the writing faces of thenibs perpendicular to a tangent to the arcuate portion at its outwardextremity.

With the above and other objects in view, the invention will behereinafter more particularly described, and the combination andarrangement of parts will be shown in the accompanying drawing andpointed out in the claims which form part of this specification.

Reference will now be had to the drawing, whereim like numerals ofreference designate corresponding parts throughout the several views, inwhich:

Figure 1 is a perspective view of the pen.

Figure 2 is a longitudinal sectional view.

Figure 3 is an enlarged fragmentary view of the nib portion.

Figure 4 is a cross-sectional view, the section being taken as on line4-4 in Figure 2.

In the illustrated embodiment of the invention the several views show apen comprising an elongated hollow tubular handle or body 10, the hollowinterior 11, serving as a reservoir for writing fluid. The nib end ofthe tubular handle is flattened and curved to form an arcuateconstricted ribbon-like outward portion or elbow 12, in obtuse angularrelation with the upper face of the tubular body and having constrictedside walls terminating in a ribbon-like orifice 13. The nib end portion14, of the body 10, is obliquely bevelled outwardly from the near side15, to the far side 16. The nib walls being longitudinally slotted, asat 17, the slots being equally spaced and extending from the outer edgesof the nibs inwardly to provide a plurality of serrations or ink bearingpoints 18, so as to insure an even discharge of the ink or other writingfluid. The outer edges 19, 20, of the nib portion have been rounded intoa substantially semicylindrical form to permit variation of the writingangle without scratching or damaging the paper or other surface writtenupon. The writing faces 21, of the nibs have been made perpendicular toa line drawn tangent to the arcuate portion 12, at its outwardextremity, as shown in Figure 3.

An elastic air-bulb 22, of any well known make, may be secured to thebody 10, in sealed relation therewith, at the end opposite the nibs forraising the writing fluid into the reservoir 11, the functioning of theair-bulb 22, being the same as that in the type of pens commonly styledfountain pens. By bringing pressure to bear against the air-bulb 22, andreleasing same, a sufficient quantity of writing fluid may be raisedinto the reservoir 11, through t e o fic a d stored in the reservoir,The body 10, may be provided with a knurled portion 23, adjacent thearcuate portion 12. The knurled portion serving to provide a morepositive grip on the handle 10.

In operation, the writing fluid flows from the reservoir 11, through thearcuate portion 12, and between the constricted nibs in an evendischarge upon the paper, the arcuate portion 12, serving to graduallychange the direction of flow and to regulate the flow of the writingfluid so that it p5 will leave the pen uniformly irrespective of thewriting angle in which the user may hold the pen, a pen of this designbeing particularly useful for persons having stiff or crooked fingersand who are compelled to hold the pen at unusual wo angles orinclinations. As shown in Figures 2, and 3, there has been provided anaperture 24, in the arcuate extremity serving as a vent hole to allowunrestricted flow of the writing fluid.

It will thus be seen that there has been provided a sign writing penhaving an elongated hollow tubular body with an arcuate outward nib-endportion 12, in obtuse angular relation with the upper face of thetubular body and with rounded outer edges of the nib portion whichpermits lettering to- Be made with a great deal of variation of thewriting angle without scratching or damaging the surface written upon.

Having thus described my invention, I claim:

1. In a device of the class described, the combination with a pencomprising an elongated hollow tubular body having an arcuate andribbonlike extremity, said arcuate extremity being positioned in obtuseangular relation with the upper face of the tubular body and beingprovided with constricted and slotted writing fluid bearing nibs, saidarcuate extremity having a vent hole, said nib portion being obliquelybevelled outwardly from the near side to the far side, the outer edgesof the nibs being rounded into a substantially semi-cylindrical form topermit change of the writing angle without scratching the writingsurface, the writing faces of the nibs being perpendicular to a tangentline drawn at the outward extremity of the arcuate portion, an elasticairbulb secured to said tubular body in sealed relation therewith at theend opposite the nib portion for filling said pen, said tubular bodybeing provided with a knurled grip portion adjacent said arcuate nibportion.

2. In a device of the class described, the combination with a pencomprising an elongated hollow tubular body having an arcuate andribbonlike extremity, said arcuate extremity being positioned in obtuseangular relation with the upper face of the tubular body and beingprovided with constricted and slotted writing fluid bearing nibs, saidarcuate extremity having a vent hole, said nib portion being obliquelybevelled from the near side to the far side, the outer edges of the nibsbeing rounded into a substantially semi-cylindrical form to permitchange of the writing angle without scratching the writing surface, andmeans secured to said tubular body for filling same with writing fluid.
